An excellent wide field EP for the C9.25 is the 30mm 1prd.

At US$95 it is excellent value and the views I get with it are stunning. Rumour is that it uses the same glass as equivalent University Optics EP, but at 1/3 of the price.
For planetary, you will probably only need a good plossl, as FOV is not particulary important. I find my Televue 17mm & 10mm plossl's very good on planetary...
Of course if you have heaps of money you'll find it hard to beat a Nagler or two!
Cheers
